Missing MXF Avid shots from RedCine X export

[Roddy Blelloch]

Client frantically emailed that they are missing clips that I exported from Red Cine X. Nothing unusual in process: imported files into bin, basic grade, then export to MXF 145/8 bit. I've done it before without incident. In fact I'd been processing the 3 prior days of shooting on build 32, before updating to 33 on final 4th day when the problem occurred. One thing I noticed comparing days 1-3 with day 4 is that build 32 exports created 3 MXF files per clip while build 33 created 5 MXF files per clip. Charles at Red workflow support told me that typically RDC files divide shots larger than 4gbs into smaller R3D files and then link them together in post which "sometimes" causes missing portions in the final clip. But my client is saying that entire clips are missing despite the fact that they appear in the lists within the export folder in the end, making it appear that everything was there.

Anyone?

Sometimes you have to take a look at the folder path with any new RC-X builds because they don't simply default to the same folders as before.

The MXF files work like this, one file is created for each audio track, plus one is created for the video track. They are not self contained files like prores, h264, etc. You can tell what the video file is because its size is always much larger. Anyway this is why the number of MXFs per clip can change, depends if there is audio and how many channels, etc...

To repeat/add on Jeremy says check your export settings for destination. It could of put them inside the raw file folder, I sometimes do that to keep it tidy on a clip to clip basis (this is also the usual default, I believe for where they go). It could of done a custom output destination somewhere, but where ever it went unless you changed the output destination since then it will give you the bread crumbs to retrace where it was set to.. You can always kick them out again obviously if needed too from the raws, but best to avoid that unless they are really lost. I'm sure you can retrace your output destination and save the day though, and now you will have a better understanding of both MXF and redcine, so all good in the end.. Best of luck!
